You Don't Have to Build Alone

One of the most underappreciated aspects of the experimental aircraft world is the community around it. The Rans builder and owner community is active, welcoming, and remarkably helpful — whether you're troubleshooting a control rigging question at 11pm or looking for someone who's already installed the exact avionics package you're considering. Finding and engaging with this community is one of the best investments you can make in your build.

EAA: The Foundation of the Homebuilt Community

The Experimental Aircraft Association (EAA) is the backbone organization for experimental aviation in the United States. For Rans builders and S-21 owners, the EAA offers several invaluable resources:

  • Technical Counselors — experienced builders who will visit your shop and review your work, free of charge. This is an incredibly valuable resource that many builders underutilize.
  • Flight Advisors — EAA members with experience in experimental aircraft who can provide guidance on test flying your newly completed aircraft
  • Chapter network — local EAA chapters hold regular meetings, fly-ins, and workshops. Finding your nearest chapter is the fastest way to connect with local builders
  • EAA AirVenture Oshkosh — the world's largest aviation event, held annually in Oshkosh, Wisconsin. The homebuilt camping area and forums are essential for serious builders

EAA AirVenture: The Annual Pilgrimage

If you own or are building a Rans aircraft, AirVenture Oshkosh deserves a prominent place on your calendar. Each year, the event draws hundreds of thousands of aviation enthusiasts, and the homebuilt area is a particular highlight. You'll find:

  • Dozens of Rans aircraft on display in the homebuilt and LSA areas
  • Builders and owners willing to open their cockpits and share what they know
  • Manufacturer representatives from Rans (the company is typically present)
  • Forums and workshops on experimental building, Rotax engines, avionics, and more

Flying in to Oshkosh in your completed S-21 is a milestone that many builders describe as one of aviation's most memorable experiences.

Regional Fly-Ins Worth Attending

Beyond Oshkosh, a number of regional events draw strong experimental and LSA attendance:

  • Sun 'n Fun Aerospace Expo (Lakeland, FL) — the second-largest U.S. airshow, with strong homebuilt participation and a warm spring date
  • Copperstate Fly-In (Arizona) — popular in the Southwest with a strong experimental contingent
  • Pacific Fly-In (various locations, Pacific Northwest) — strong regional following among light aircraft builders
  • Local EAA chapter fly-ins — often the most relaxed and builder-friendly environment to show your aircraft or get shop talk going

Online Communities for Rans Builders

The internet has dramatically changed the build experience. Online communities mean you're never more than a few hours from a knowledgeable answer to a specific build question. Key places to engage:

  • Rans Aircraft Owners & Builders groups on Facebook — active discussion, build photos, and a searchable history of common questions
  • VAF (Van's Airforce) Forums — while primarily Van's RV-focused, this is the largest experimental builder forum and has relevant threads on Rotax, avionics, and general building technique
  • EAA's online forums and member resources — particularly useful for regulatory questions
  • YouTube build channels — several Rans S-21 and S-19 builders document their projects on video, providing visual walkthroughs of specific build steps

The Rans Factory: Hays, Kansas

Rans Aircraft is based in Hays, Kansas, and the factory is known for being accessible and responsive to owners and builders. The company offers factory tours and the staff are generally willing to answer technical questions. If you're close enough for a visit during the build process, it's well worth the trip — seeing how the factory assembles the aircraft provides clarity that no manual can fully replicate.

Building Community Into Your Build

The most successful builders tend to be those who treat the build as a community endeavor rather than a solo project. Share your progress, ask questions early (before you make an irreversible mistake), and pay it forward when newer builders ask the questions you once asked. The light sport experimental community is one of aviation's most welcoming corners — take full advantage of it.
